Cygwin: python dial_tone.py Segmentation fault

I performed the steps as shown in
http://gnuradio.org/trac/wiki/CygwinInstallMain to install gnuradio in
Cygwin. All building process produces no errors.
However, when I try the dial_tone.py example, it doesn’t work with segv.

$ python dial_tone.py
Segmentation fault (core dumped)

$ cat python2.4.exe.stackdump

Any help?
